Disclosure of Invention

The object of the invention is to provide a household appliance having an input device which can be assembled in a simple manner and repaired in a simple manner if necessary.

This object is achieved by a household appliance, in particular a refrigerator, having an electronic control unit which is designed to control at least one function of the household appliance and which comprises an electronic control circuit board and an input device which is connected to the control circuit board and which has at least one input element and which is designed to supply a slave control signal to the control circuit board on the basis of a manual actuation of the input element, wherein the input device has a flexible carrier which is arranged on the rear side of at least one partially at least light-permeable wall of the household appliance and on which the at least one input element is arranged, characterized by a pressing device which is designed to press the flexible carrier at least partially against the rear side of the at least partially at least light-permeable wall.

In this context, the at least partial pressing of the flexible carrier against the rear side of the wall means that the flexible carrier presses either against the rear side of the wall over the entire surface or only against one or more partial surfaces of the flexible carrier, for example, a plurality of square or rectangular partial surfaces spaced apart from one another, in particular also only against the rear side of the wall in a point-like manner.

The input device may generally have a pressure device. This may mean that the pressing device is part of the input device, or that the pressing device, although forming a separate component, is connected to the input device, or at least coupled to the input device.

In all configurations, the flexible carrier can be configured as a touch film or a touch screen. The touch film or touch screen may herein comprise, i.e. have, an input device.

The at least partially at least light-transmitting wall can be formed transparent at least in this section. The wall can be formed, for example, in a generally light-transmitting manner, as a glass wall, which is optionally transparent in glass, i.e. clear or only opalescent, for example by grinding or etching. The wall can be completely transparent or have only a number of segments of window-like transparency, which are at least transparent or even clear, wherein the segments of window-like transparency can form the surrounding region in an opaque manner, for example can be made of opaque plastic or metal.

By providing the pressing device, which is designed such that the flexible carrier presses against the rear side of the transparent wall body, the flexible carrier can be reliably positioned on the rear side of the transparent wall body in a safe manner, thereby ensuring a safe, functionally sound contact of the flexible carrier with the transparent wall body. On the one hand, it is ensured that the flexible carrier bears against the rear side of the transparent wall without air gaps, folds and/or waves, and on the other hand, the known full-surface bonding of the flexible carrier to the transparent wall can be dispensed with. The flexible carrier can also be connected to the back of the transparent wall without adhesive bonding by means of a pressing device. The flexible carrier can be detached from the transparent wall and/or reattached to the transparent wall repeatedly and without damage by means of the adhesive-free ground connection.

The pressing device can be designed such that the flexible carrier is pressed against the rear side of the transparent wall on one or more partial surface sections of its surface facing away from the transparent wall. The pressing device can be designed in particular such that the flexible carrier is pressed against the rear side of the transparent wall on those partial surface sections which are illuminated with light from the light channel forming the touch-sensitive area of the touch-sensitive display screen.

The pressure means can be formed on the light-conducting element, in particular by the light-conducting element, which can have one or more light channels or light wells, which are designed to guide light emitted by at least one light-emitting electrical element, in particular arranged on the electronic control circuit board, onto the surface of the flexible carrier facing away from the transparent wall, or to prevent light from escaping to adjacent display areas and/or operating areas.

The light-conducting component can have one or more light channels or light wells, which can be designed to conduct the light emitted by at least one light-emitting electrical component, for example at least one L ED, in particular L ED, which is provided on the electronic control circuit board, to the rear side of the flexible carrier.

The pressing device can be formed by one or more light channels or light wells, which are elastically supported on the light-conducting element in such a way that, in the arrangement of the input device mounted behind the transparent wall, the flexible carrier is pressed against the rear side of the transparent wall by the elastically supported light channels.

The pressure device can have a short flexible arm section on the light-conducting element for the elastic support of the light channels or light wells, which connects each individual light channel or light well to the light-conducting element in an elastic manner. The short arm section can connect the respective light channel or light well, in particular with an S-shaped extension, to the light-conducting member. The short arm section, the light channel or the light well and the light-conducting member may be constructed as an integral plastic injection-molded part.

The resiliently supported light tunnel 19 may have a light funnel 36 with a tapered wall 37. On the outer surface of the conical wall 37, a short arm section 35 can be arranged and in particular extends outward in an S-shape, where it ends at a base frame section 38 of the light-guiding member 13 a. The base frame section 38 can have an end wall 39, which presses the flexible carrier 12b against the rear side of the transparent wall 8 in the assembled, pressed state. The annular end wall 40 of the light funnel 36 can project out of the plane of the end wall 39 of the base frame section 38 in the relaxed state, i.e. in the unassembled state of the elastically mounted light tunnel 19. When the end wall 39 is in the assembled, pressed state against the rear side of the transparent wall 8, the light funnel 36 is deformed by its projection against the rear side of the transparent wall 8 in the region of the short limb section 35 with simultaneous clamping of the flexible carrier 12b, and is thereby pretensioned, whereby the annular end wall 40 of the light funnel 36 is pressed from behind against the rear side of the transparent wall 8.

In all configurations, the transparent wall can be formed by a surface section of the actuating panel, a surface section of the front pane and/or a surface section of the glass door leaf.

The input device can generally have a fastening means, on which the flexible support is fastened in a tensioned manner by means of at least one form-and/or force-locking fastening means connected to the fastening means.

A tensioned fastening is to be understood to mean, in particular, a form-and/or force-fitting fastening of the flexible support, in which case a tensile force acts on the flexible support, which tensile force extends in the plane of the flexible support and thus extends the flexible support at least in one direction, preferably in two orthogonal directions, within the plane of the flexible support, so that the flexible support is fastened to the fastening means without bending, folding, waves and in particular in a planar manner, in particular is placed on the fastening means in a planar manner. If the fastening means are designed as light-conducting members, the flexible carrier can be fastened to the light-conducting members without bending, folding, waves and, in particular, flat. In particular, a tight fastening is to be understood to mean that the flexible support is fastened only to the edge of the fastening means and lies in the center section only on the rear side of the transparent wall by means of the pressure means.

The securing mechanism may be designed to repeatedly detach the flexible carrier from the securing facility and/or to re-secure the flexible carrier on the securing facility without damage.

The fastening means has at least one, in particular two, rigid fastening means spaced apart from one another, which are designed to fasten a first end section of the flexible carrier, and the fastening means can have at least one, in particular two, elastic fastening means spaced apart from one another, which are designed to fasten a second end section of the flexible carrier opposite the first end section.

The rigid fastening means may be formed by two upwardly projecting rigid tongues formed on the fastening means. For each rigid tongue of the fastening device, a circular, oval or oblong hole can be provided in the flexible carrier. For example, two elastic fastening means can be formed on the fastening means at the end of the fastening means end face opposite the rigid fastening means. The elastic fixing means can in this case be formed by two upwardly projecting elastic tongues formed on the fixing facility. For each spring tongue of the fastening device, a circular, oval or oblong hole can be provided in the flexible carrier. In the tensioned assembly arrangement, each rigid and elastic tongue is pressed into a hole in a form-fitting manner. The flexible carrier is tensioned by the elastic fastening means, in particular the spring or the elastic structure of the elastic tongue, and is loaded with a tensile force acting in the plane of the flexible carrier, so that the flexible carrier extends in a very planar manner in alignment with the top side of the fastening means. Due to the positive connection of the rigid and elastic tongues to one hole, respectively, the flexible carrier can be repeatedly detached from the fastening device without damage and can be fastened to the fastening device again at any time or replaced by another flexible carrier. This allows, for example, a defective touch film to be replaced in a simple manner by a new, fully functional touch film. In particular, the touch film already mounted can be removed from the fastening device without damage.

In all configurations, the input device may have a flexible carrier on which at least one input means is arranged, the input device may have a touch screen, the flexible carrier may form a sensing surface of the touch screen, and the at least one input means may be formed by surface portions of the sensing surface, in particular surface portions of the sensing surface pertaining to those light channels.

In order to fix the preassembled loading device in a flat contact manner on the rear side of the transparent wall, a clamping device may be provided, which is designed to open between the rear side of the preassembled loading device and the inner wall of the light well in a position inserted behind the transparent wall, in particular the front glass pane, the front glass or the glass door leaf, whereby the loading device is pressed against the front glass pane, i.e. the rear side of the front glass pane or the rear side of the glass door leaf.

The invention therefore relates to a household appliance, in particular a refrigerator, a hob, a cooking area, a range hood, a dishwasher, a washing machine, a dryer or an automatic coffee machine, which has an input device according to the invention as described above.

Detailed Description

The household appliance 1 illustrated by way of example in fig. 1 is configured as a refrigerator 1 a. The refrigerator 1a has a cabinet 2. An insulated inner container 3 is arranged inside the cabinet 2. The inner container 3 delimits a storage chamber 4 for refrigerated goods, in particular food products. One or more partitions 5, in particular glass partitions, can be arranged in the inner container 3 for storing the food. The front access opening of the storage chamber 4 can be closed by a door leaf 6. In the present exemplary embodiment, the door leaf 6 is mounted so as to be pivotable about a vertical pivot axis on the basis of the inner container 3. For this purpose, the door leaf 6 can be hinged, for example, to the cabinet 2 or the inner container 3 by means of a hinge, not shown in detail. One or more door brackets 7 can be arranged on the inner side of the door leaf 6 facing the storage chamber 4, as shown in fig. 1. The door leaf 6 can optionally have a front glass plate 8a or a front metal plate 8b on its outer side. Alternatively or additionally, the door leaf can have an actuating panel 9 on the outside. The control panel 9 can be made of plastic, in particular transparent plastic, or have at least one transparent window section 10. In a special embodiment, the transparent window section 10 can be formed solely by the region of the front glass pane 8 a.

In the region of the transparent window section 10, the household appliance 1 or the refrigerator 1a has an input device 11. The input device 11 is arranged in particular behind the control panel 9 or the front glass plate 8a or the front metal plate 8 b. The input device 11 has at least one input means 12, which is designed to control a function of the household appliance 1 on the basis of manual actuation of the input means 12. In the present case at least one input device 12 is formed by a touch screen 12 a.

Fig. 2a shows an example configuration of the input device 11 in an exploded view. The input device 11 therein comprises an input device 12, in particular a touch screen 12a, a stationary installation 13 and an electronic control device 14. The electronic control device 14 has an electronic control circuit board 14 a. The electronic control device 14, in particular the electronic control circuit board 14a, is designed to control at least one function of the household appliance 1, in particular the refrigerator 1 a. For this purpose, at least one input device 12, in particular a touch screen 12a, is electrically connected to an electronic control device 14, in particular an electronic control board 14a, by means of electrical connecting lines 15. When the input device 12 or the touch screen 12a is actuated manually, the associated control signals are routed to the control circuit board 14a via the connecting lines 15.

The input device 11 also has a flexible carrier 12b on which the at least one input means 12 is arranged in the present case, and the flexible carrier has a touch screen 12a, wherein the flexible carrier 12b forms a sensing surface 12c of the touch screen 12a and the at least one input means 12 is formed by a surface portion of the sensing surface 12 c.

The input device 11, in particular the input means 12 or the touch screen 12a, therefore has a flexible carrier 12 b. This means that the flexible carrier 12b has at least one input device 12. In the case of the touch screen 12a, the flexible carrier 12b is designed as a touch film, which forms a sensor surface 12c, which can detect a hand contact and can also provide a signal via the position at which the hand contact occurs.

The flexible support 12b is fixed in tension on the fastening device 13 by at least one form-and/or force-locking fastening means 16 connected to the fastening device 13.

The fixing mechanism 16 is designed to repeatedly detach the flexible carrier 12b from the fixing facility 13 without damage and to re-fix the flexible carrier 12b on the fixing facility 13.

For this purpose, in the exemplary embodiment shown, the fastening device 13 has at least one rigid, in particular two rigid fastening means 16a spaced apart from one another, which are designed to fasten a first end section 17a of the flexible carrier 12b, and also has at least one elastic, in particular two elastic fastening means 16b spaced apart from one another, which are designed to fasten a second end section 17b of the flexible carrier 12b opposite the first end section 17 a.

The rigid fastening means 16a are formed in the present case by two rigid tongues formed on the fastening device 13 and projecting upwards. A circular, oval or oblong hole 18 is provided in the flexible carrier 12b for each rigid tongue of the fastening means 13. Two elastic fixing means 16b are formed on the fixing means 13 at the end of the end face of the fixing means 13 opposite to the rigid fixing means 16 a. The elastic fastening means 16b are formed by two upwardly projecting elastic tongues formed on the fastening facility 13. A circular, oval or oblong hole 18 is provided in the flexible carrier 12b for each spring tongue of the fastening means 13. In the tensioned installation configuration, each of the rigid and elastic tongues engages in a hole 18 in a form-fitting manner. The flexible support 12b is tensioned by the elastic fastening means 16b, in particular the elastic structure of the spring tongue, and is loaded with a tensile force acting in the plane of the flexible support 12b, as a result of which the flexible support 12b extends in a very planar manner in alignment with the top side of the fastening means 13. Due to the positive connection of the rigid and elastic tongues to one of the holes 18, the flexible carrier 12b can be removed repeatedly and without damage from the fastening device 13 and can be fastened to the fastening device 13 again at any time or replaced by another flexible carrier 12 b. This allows, for example, a defective touch film to be replaced in a simple manner by a new, fully functional touch film. In particular, the touch film already mounted can be removed from the fastening device 13 without damage.

In the exemplary embodiment according to fig. 3 and 4 in particular, the fastening means 13 are formed on a light-conducting element 13a, or the fastening means 13 are formed by a light-conducting element 12a, the light-conducting element 13a in this case having one or more light channels 19 which are designed to guide the light emitted by at least one light-emitting electrical element 20, in particular at least one L ED20a, in particular L ED20a provided on the electronic control circuit board 14a, to the rear side of the flexible carrier 12b, so that the fastening means 13 or the light-conducting element 13a can be produced from a transparent plastic element, in particular a plastic injection-molded part, and in addition to the light channels 19 formed in this way on the fastening means 13, further, also independent light conductors 19a can be provided, as shown in fig. 4.

The light-guiding component 13a furthermore has first holding means 21, which are designed to fix the electronic circuit board 14a to the light-guiding component 13a in a form-fitting manner. Each first holding mechanism 21 is formed of a first positioning hook 21a in the case of the present embodiment. Each positioning hook 21a is formed integrally with the light-guiding member 13a and comprises an elastic rod section and a positioning hook arranged on the free end of the elastic rod section. In the assembled state, the latching hooks 21a, in particular the latching projections, form-fittingly enclose the associated edge section of the electronic circuit board 14 a. It is thus possible to position the electronic circuit board 14a on the light-guiding member 13 a.

In a first embodiment variant according to fig. 3, the household appliance 1, in particular the refrigerator 1a, has a control panel 9 and a fixing frame 22. In this embodiment variant, the fastening frame 22 is arranged on the rear side of the control panel 9, in particular is formed integrally with this control panel 9. The structural components of the input device 11, which comprise at least the input means 12 or the flexible carrier 12b, in particular the touch screen 12a, the fastening means 13 or the light-conducting member 13a, and the electronic control circuit board 14a, are fixed to the rear side of the control panel 9 by means of the fixing frame 22 in a form-fitting manner.

For this purpose, the fastening frame 22 has second holding means 23, which are designed to fasten the light-conducting component 13a and thus the assembly of the input device 11, which assembly comprises at least the input device 12 or the flexible carrier 12b, in particular the touch screen 12a, the fastening means 13 or the light-conducting component 13a, and the electronic control circuit board 14a, to the fastening frame 22. Each second holding mechanism 23 is configured as a second positioning hook 23a in the case of the present embodiment. Each positioning hook 23a is formed integrally with the fastening frame 22 and comprises an elastic rod section and a positioning projection arranged on the free end of the elastic rod section. In the assembled state, the second positioning hooks 23a, in particular the positioning projections, form-fittingly enclose the associated edge section of the light-guiding member 13 a. The light-guiding member 13a or the entire preassembled input device 11 can therefore be positioned on the fixing frame 22 and thus also on the operating panel 9.

In the second embodiment variant according to fig. 4, it corresponds essentially to the configuration according to fig. 3, but instead of the fastening frame 22 being formed integrally with the operating panel 9, the fastening frame 22 is formed by a separate component, i.e. a component separate from the operating panel 9.

In this second embodiment variant according to fig. 4, the fastening frame 22 can be arranged on the rear side of the front glass pane of the household appliance 1 or refrigerator 1a, in particular on the rear side of the glass door leaf.

For this purpose, as is shown in fig. 1, a slot 24 is provided behind the rear side of the front glass pane, i.e. the front glass 8a, or on the rear side of the glass door leaf of the household appliance 1 or the refrigerator 1a, into which the pre-assembled input device 11 (fig. 2 b) is inserted and can be fixed there in such a way that the tensioned flexible carrier 12b, in particular the touch screen 12a, rests flat against the rear side of the front glass pane, i.e. the front glass 8a, or against the rear side of the glass door leaf.

In order to fix the preassembled fitting 11 (fig. 2 b) in a flat contact manner on the rear side of the front glass pane, i.e. the front glass 8a, or on the rear side of the glass door leaf, a clamping device 25 can be provided, which is designed to open between the rear side of the preassembled fitting 11 (fig. 2 b) and the inner wall of the insertion slot 24 in the position inserted into the insertion slot 24, so that the fitting 11 is pressed against the rear side of the front glass pane, i.e. the front glass 8a, or the rear side of the glass door leaf.

Such an exemplary clamping device 25 is shown in detail in fig. 5c and 5 d. The clamping device 25 has in this case an end plate 26 and four tines 27. The end panels 26 are designed to connect and collectively secure the tines 27. The end plate 26 can also form a gripping section which can be gripped manually for the purpose of introducing the four tines 27 together into the insertion groove 24 (fig. 1) and retaining them therein. The four tines 27 extend at a distance from one another and are oriented parallel to one another and are fixed to the end plate 26, in particular are formed integrally with the end plate 26.

Each tine 27 forms a wedge. Each wedge cooperates in the mounted position of the clamping device 25 with obliquely running bevels 28, which are arranged on a bottom surface 29 of the rear side of the fixing frame 22 (fig. 4). By inserting the tines 28 laterally under the bottom surface 29 of the rear side of the fixed frame 22 and by supporting the clamping device 25 in the mounted position against the rear wall 30 of the insertion slot 24 (fig. 1), the fixed frame 22 is pressed by inserting the clamping device 25 against the rear side of the front pane, i.e. the front pane 8a, or against the rear side of the glass door leaf.

For this purpose, each tine 27 has an obliquely running bearing surface 31, to which three spring tongues 32 are fastened, which are arranged at the same distance from one another in the longitudinal direction of the tine 27. The spring tongues 32 are elastically prestressed when the clamping device 25 is inserted into the insertion groove 24 (fig. 1) and, in the final installation position, press the fastening frame 22 against the front glass pane, i.e. against the rear side of the front glass 8a or against the rear side of the glass door leaf. The spring tongue 32 is supported on the obliquely running inclined surface 28 of the fixing frame 22.

To ease the insertion of the clamping device 25 along the back of the fixed frame 22 and to prevent jamming and/or jamming, each tine 27 has a guide strip 33. Each guide strip 33 extends in the longitudinal direction of the tines 27, which is also the insertion direction. All guide strips 33 extend parallel to one another. A corresponding guide groove 34 is provided for each guide bar 33. The guide groove 34 is arranged on the rear side of the fixing frame 22, in particular is formed integrally with the fixing frame. The guide groove 34 is arranged in the present exemplary embodiment along the obliquely running inclined surface 28 of the fixing frame 22 or is formed integrally therewith. The guide strip 33 slides in the guide groove 34 during insertion of the clamping device 25 into the insertion groove 24.

As shown in fig. 6a to 6d, the light-guiding member 13a has one or more light channels 19. In order to exert an additional pressing force, which presses the flexible carrier 12b as flat as possible against the rear side of the actuating panel 9, the rear side of the front glass pane, i.e. the front glass 8a, or the rear side of the glass door leaf, in the present exemplary embodiment each light channel 19 is elastically supported on the light-conducting element 13a in such a way that, in the arrangement of the input device 11, in particular the light-conducting element 13a, which is mounted behind the actuating panel 9, the front glass pane, i.e. the rear side of the front glass 8a, or the rear side of the glass door leaf, the flexible carrier 12b tensioned on the fastening means 13, in particular the light-conducting element 13a, is pressed against the rear side of the actuating panel 9, the front glass pane, i.e. the front glass 8a, or the glass door leaf via the elastically supported.

For elastic support of the light channels 19, elastic short arm sections 35 can be provided on the light-guiding member 13a, which elastically connect each individual light channel 19 to the light-guiding member 13 a. Each short arm segment 35 may connect the respective light channel 19 with the light-guiding member 13a in an S-shaped extension. The short arm segment 35, the light channel 19 and the light-guiding member 13a may be made as an integral plastic injection-molded part.

As shown in fig. 7a and 7b, the elastically supported light tunnel 19 has a light funnel 36 with a conical wall 37. On the outer surface of the conical wall 37, in the present exemplary embodiment, a short limb section 35 is arranged, and in particular extends in an S-shape outward, where it terminates in a base frame section 38 of the light-conducting member 13 a. The base frame section 38 can have an end wall 39 which, in the assembled, pressed state (as shown in fig. 7 b), presses the flexible carrier 12b against the rear side of the transparent wall 8. The annular end wall 40 of the light funnel 36 can project out of the plane of the end wall 39 of the base frame section 38 in the relaxed state, i.e. in the unassembled state (as shown in fig. 7 a) of the elastically mounted light tunnel 19. When the end wall 39 is in the assembled, pressed state according to fig. 7b against the rear side of the transparent wall 8, the light funnel 36 is deformed by its projection against the rear side of the transparent wall 8 in the region of the short limb 35 with simultaneous clamping of the flexible carrier 12b, and is thereby pretensioned, so that the annular end wall 40 of the light funnel 36 presses the flexible carrier 12b from behind against the rear side of the transparent wall 8.
